Compatibility with hosts is often problematic as Git and proc_open() are required on the server. See Hosting and System requirements.

Be familiar with WordPress and Git.

You can tell whether you are using a Developer Preview / Early Access release of VersionPress from the top admin bar.

Note on 'Early Access' and 'EAP'

Between January 2015 and March 2016, VersionPress used to be available through the Early Access Program (EAP). It was discontinued when VersionPress moved to a fully open development model in April 2016.

Between April 2016 and May 2017, the term "Early Access" was used. We then switched to "Developer Preview" which better indicates the project status. See issue #1201.
